摘　　要：本研究使用胶原蛋白与苯基膦酸进行反应,制备了磷氮协效阻燃剂胶原蛋白/苯基膦酸盐(POC)。使用浸渍烘干法将其整理到涤棉混纺织物(PTCO)上,详细研究了阻燃整理PTCO的微观形貌、热稳定性能、阻燃性能、燃烧行为、力学性能、抗菌性能及阻燃机理等。扫描电子显微镜图片表明POC均匀地沉积在PTCO的表面。空气氛围下PTCO/POC的R_(max)降低了20.3%,700℃下的残炭由0.6%提升至3.3%。PTCO/POC在垂直燃烧中能够自熄,续燃时间与阴燃时间都为0 s,损毁长度为7.8 cm,LOI值为28.2%。在CCT测试中点燃时间由26 s延长至35 s,最大热释放速率与总热释放分别降低了33.8%和23.6%。此外,PTCO/POC保留了88.1%的断裂强力。PTCO/POC对大肠杆菌和金黄色葡萄球菌的抑菌率均达到了99.99%。综上所述,PTCO/POC兼具阻燃性能与抗菌性能。In this study,a P/N synthesized flame retardant,POC,was prepared by reacting collagen with phosphenylic acid(PPOA),and used to improve the flame retardancy of polyester cotton blended fabrics(PTCO)by the dip‒drying method.A detailed study was conducted on the microstructure,thermal stability,flame retardancy,combustion behavior,mechanical properties,antibacterial properties,and flame‒retardant mechanism of finished PTCO.The scanning electron microscope images indicated that POC was uniformly deposited on the surface of PTCO.The R_(max) of PTCO/POC under air atmosphere decreased by 20.3%,and the char residues at 700℃increased from 0.6%to 3.3%.PTCO/POC can self‒extinguish,with an afterflame time and afterglow time of 0 s,a damaged length of 7.8 cm,and an LOI value of 28.2%.In cone calorimeter test,the time to ignition was extended from 26 s to 35 s,and the peak heat release rate and total heat release values were decreased by 33.8%and 23.6%,respectively.In addition,the breaking force of PTCO/POC was increased from 725 N of PTCO/PPOA to 810 N,remaining 88.1%of the breaking force compared with that of PTCO.The antibacterial rates of PTCO/POC against Escherichia coli and Staphylococcus aureus both reached 99.99%.In summary,PTCO/POC owned better flame retardancy and antibacterial properties.
